Don't miss the purpose of the video...
The purpose of the video was to show how quickly and easily you can generate a DXF file from an actual part. For fabricating one-off parts (either on a laser, plasma table, or CNC machine) you can save a lot of time having to create a file in your CAD or modeling software.
As someone who has spent a lot of time working with machinery and systems that are no longer supported, this could be a godsend. If I could have a database of commonly used gaskets and a laser cutter I could reduce my inventory on board, as well as not having to have someone spend half an hour making a gasket. Especially when dealing with the very thin compressed sheet packing material, which always seems to crack or tear on the last cut. The expensive gaskets we buy from OEM suppliers have a bad habit of dying in storage if not used in a couple of years after purchase.
I could definitely see this sort of tech employed in the not so distant future. It could be as common place as the milling machine, lathes, and welding equipment we employ today.
